LOCOMOITVE-JOURNAL-BOX-LUBRICATING' APFARATUS.

Application filed October My invention relates to improvements inlocomotive journal box lubricating apparatus.

The principal object of my invention is to provide an improvedperforated plate whereby the waste of grease or lubricant is reduced toa minimum.

Another object is to provide improved plates which will retain theirshape longer than will the plates at present in common use.

Other objects relate to features of construc tion and arrangement ofparts, which will become apparent from a consideration of the followingspecification and accompanying drawings, wherein- Figure 1 is aconveniental driving box showing one form of my perforated platetherein.

Fig. 2 is a longitudinal sectional view taken on line 2-2, Fig. 1.

Fig. 3 is a perspective view of another form of my invention, and

Fig. 4 is a view showing the relation of the locomotive axle to theplate illustrated in Fig. 3.

In locomotives of common type, the driving boxes are supplied withlubricant, usually in the form of cakes of grease, moulded to suitableshape and size, which cakes .are gradually fed to the friction surfacesof the axles through foraminous plates by means of spring actuatedfollowers. A foraminous plate, of the type referred to, is usuallyconstructed of sheet metal, such as steel, and has an upper surfacecurved to closely contact with the lower portion of the axle. Rotationof the axle in one direction more than in the other causes the plat-e tobecome somewhat deformed, which in time renders the same unsuitable forfurther service.

The plate has vertical side extensions which extend downwardly one-halfthe depth of the cellar, and in the space between the upper portion ofthe sides and the curved portion of the plate the grease often burns orcarbonizes, rendering the same unfit for use. This grease which thus iswasted must be removed, and the plate cleaned before fresh lubricant issupplied. These defects cause considerable waste, both 30, 1925. SerialNo. 65,773.

' in materials and in time involved in correcting them, and it is to aremedy of these de fects that my invention is directed.

In the drawings, 10 is a conventional driving box having a brass orhearing 11, which rests upon the locomotive driving axle 12. Suitablysupported in the lower portion of box 10 is the cellar 18, which isusually formed of cast iron. A follower plate 14: in the cellar 13 isurged upwardlyby' a spring 15' andmaintains a cake of re 16 against thelower surface of the trorated or foraminous plate, indicated, generally,by numeral 1'! in Figs. 1 and 2. This plate 17 is usually formed ofsheet metal and has a perforated curved portion 17 which contactswiththe axle 12, a pair of vertical extensions or side members 17" whichextend downwardly to approximately one-half the depth of the cellar 13,and end flanges 17 which assist in retaining the lubrieant in position.The axle in turning carries grease from the perforations in the plate17, as will be clear. The follower 13 is urged upwardly with sufficientforce only to maintain the grease in contact with the curved portion 17of the plate 17. A pair of eye bolts 18 projects from the follower 13and constitute means for retracting the follower when fresh lubricant isto be supplied, and also indicate by their exposed portions the amountof the unconsumed grease. j

The form of the plate 17, shown in Fi s. 1 and 2, corresponds to thepresent day conventional plate. I have shown, however, filler members 19in the spaces formed between the upper portions of the sides 17 and theperforated portion 17 of the plate 17. It is in these spaces that thegrease burns or carbonizes in use, resulting in considerable waste wherethe present type of plates is used. The fillers 19 may be of wood,secured in position by any suitable fastening means. The fillers 19prevent the grease from entering the upper spaces of the plate, as willbe seen, and also render the plate as a whole more rigid, thus preventing the reduction in the angle between the portion 17 at one sidewith the adjacent vertical portion 17 and the corresponding displacementof the portions on the other 21 are also provided.

i:le of member 17, which is caused by the rotation of the axle largelyin one direc- -'.o-.

End plates, of conventional form, but not shown here, are pivot-ed, .asat 20, to the box 10 to prevent entrance of dust, etc., into the drivingbox.

A modified form of my'invention is shown in Fig. 3, and comprises aplate, indicated, generally, by numeral 21, having vertical sides 21curved perforated portion 21" and inclined walls 21. The usual endflanges The inclined walls 21 may be formed integrally with side walls21 and have their upper edges welded or otherwise secured to the lowersurface of portion 21 Fig. 4 is a diagrammatic representation of alocomotive axle 22 and my plate 21 showing their relation when in adriving box (not shown), such as that previously described. It will beseen that the inclined walls 21 function similarly to the tillers 19 ofthe previously described form, in that they render the plate rigid andtend to direct the grease adjacent the side walls ob- 'liquely towardthe perforated portion of the plate, and eliminate the space tound inthe present day types of plates in which the grease collects and becomesunfit for use.

Both forms of my invention herein shown and described are adapted foruse in a standard journal box without modification thereof.

Although I have shown certain forms of my improvements for the purposeof illus' tration, it will be seen that modifications may be madetherein without departing from the spirit of my-invention, and I do notwish to be restricted to the forms shown except as limitcdthereto by theappended claims.

What I claim is: V

1. A grease plate having a pair of vertical side members, a curvedtoraminous section, and inclined walls extending from said verticalwalls to said curved portion.

2. A grease plate having a pair of ver tical side members, a curvedforaminous section, and inclined walls integral with said side membersand said toraminous section.

53. An article of the class described comprising a curved foraminousportion, and a pair of vertical side walls terminating in inclinedmembers extending inwardly and upwardly into contact withthe lowersurface of said ioraminous portion. .7

42. An article of the class described, comprising a pair of side walls,a curved l oraininous portion, and inclined means between Ffllil wallsand section secured to and adapted to brace the same against deformatiAn article ot the class described comcurved plate having lateralimperiorate 8003210118 and an ntermediate forami nous section, andrelatively stationary in- (lined means below said impertorate sectionsbricant away from said imperi or ate sections an i toward saidforaminous section.
